As roof-mounted silicon photovoltaic solar panels become cost-competitive with traditional energy-delivery methods across most of the US, prices are suddenly spiking for the silicon that makes them work.
Silver, another key raw material in the panels, is down this week.
With a 19.0% increase over the past week, silicon was the biggest mover on the weekly Renewables MMI®. The past week saw Chinese steel plate close at CNY 3,030 ($492.30) per metric ton after a 7.9% decline. The price of Chinese cobalt cathodes rose 2.3% to CNY 220,000 ($35,745) per metric ton after falling 0.9% during the previous week. The price of neodymium fell 1.4% over the past week to CNY 345,000 ($56,054) per metric ton. This was the third week in a row of declining prices.
At JPY 80,000 ($676.10) per metric ton, the price of Japanese steel plate did not change since the previous week. Closing at KRW 900,000 ($818.02) per metric ton, Korean steel plate remained unchanged for the week. Chinese steel plate saw a 7.9% drop-off this week to end at CNY 3,030 ($492.30) per metric ton. US steel plate prices fell to $816.00 per short ton, down from $843.00 a week ago.
US grain-oriented electrical steel (GOES) held steady on Tuesday, remaining around $2,731 per metric ton.
